Data

This data release contains three data sets. The data were collected in 1996 at the South Unit of Theodore Roosevelt National Park, ND, USA. The main data set comprises the list of plant species observed and includes the transect, plot number, plot size, and vegetation type where each species was found. A second data set has the locations of the transects, along with their IDs which can be linked t

Fifty-one tidal marsh sites across five regions (sub-embayments) were surveyed in the Delta, Suisun Bay, San Pablo Bay, central San Francisco Bay, and South San Francisco Bay. Vegetation surveys spanned ten years, from July 2008 to January 2018. A total of 5,112 plots were surveyed. Plots were positioned on transects along an elevation gradient and evenly distributed across each site, where possib

Harmful algal blooms (HABs) have recently been observed in rivers, including the Illinois River in the Midwest United States. The Illinois River Basin has a history of eutrophication issues, primarily caused by the excessive loading of nitrogen and phosphorus from urban and agricultural sources. Recent events have seen the emergence of cyanobacterial harmful algal blooms in the area. This data rel

This USGS data release presents data used to estimate and summarize where and when recharge occurs to the Columbia River Basalt Group (CRBG) in the Umatilla River basin, Oregon, 2014–2022. The supplemental data consist of two child items. The child items are: (1) Discrete geochemical data for groundwater and surface water samples in the Umatilla River basin, 2014–2022, and (2) Dissolved gas solu

This dataset includes pipe-flow monitoring data in sewers used to analyze the water budget at RecoveryPark in Detroit, Michigan. These are provided as 3 text comma separated format files at sewer locations that drain the study area. In addition, there are 6 text comma separated format files containing the Rhodamine dye tracer concentrations collected in the combined sewer locations for this study.

Multibeam and sidescan sonar were collected for a total of 15 sites in the North Arm, Maxwell Bay, and St. Albans Bay of Lake Minnetonka, Minnesota, to determine whether hydroacoustics could be used in turbid rivers and lakes as a method of rapid detection for invasive zebra mussel (Dreissena polymorpha) infestations. Hydroacoustic data were collected in June, August, and the end of September, 202

This is the mortality and water quality data for 2 efficacy trials of medicated feed for controlling mortality in Walleye (Sander vitreus) due to motile aeromonad infections. Top-coated feed with florfenicol or oxytetracycline or control feed were administered in both trials to fingerling walleye. Daily mortality counts and water quality measurements for dissolved oxygen, pH, temperature are inclu

This data release presents point data associated with the geologic and geophysical maps of the Sierra Nevada Digital Earth Science Atlas led by the California Geological Survey and U.S. Geological Survey. Data include principal fact information for new gravity measurements collected by the U.S. Geological Survey from 2012 to 2023 and for existing gravity measurements compiled from 21 sources. Near

On February 14th, 2019, a strong atmospheric river storm (AR4 on the Atmospheric River scale of Ralph et al., 2019) struck California. The heavy rainfall caused landslides in both northern and southern California (Hatchett et al., 2020). This data release includes two subsets of mapped shallow landslide source locations in the vicinity of western Riverside County, California, where sufficient post

Field observations in a Lake Ontario embayment suggested that there is a phototaxic response of larval cisco that changes with development. This switch was verified using cultured cisco in a laboratory environment. These data include counts of cisco larvae at three depth ranges within multiple 95 liter tanks. Each tank of larvae were exposed to one of three different light treatments with three re

In cooperation with the South Carolina Department of Transportation, the U.S. Geological Survey updated the foundational geospatial layers for the South Carolina StreamStats web application (https://water.usgs.gov/osw/streamstats/), which provides analytical tools useful for water-resources planning and management (Kolb and others, 2018). This dataset presents the digital elevation model, lidar-de

The area surrounding La Conchita, California (CA), USA experienced significant landslides and debris flows following a storm on January 10th, 2005, including a deadly deep-seated landslide that destroyed 13 houses and caused 10 fatalities (Jibson, 2006). This data release documents the locations of shallow landslide source locations in the vicinity of the deadly 2005 La Conchita landslide. Landsli
